ABSTRACT
Professional development, the search for economic stability and personal fulfillment have been some of the reasons why an increasing number of women have decided to delay pregnancy beyond the third decade of life. By definition, a pregnancy of advanced maternal age is considered to be those over 35 years of age, and it is known that this age group faces a higher risk of complications during pregnancy, intrapartum and postpartum, in addition to perinatal morbidity and mortality that is usually associated with chromosomal abnormalities. In Chile, pregnancies over 35 years of age or late pregnant women have increased significantly in recent decades, however there are no statistical data at a local level. The objective of this study is to evaluate the prevalence of pregnancies of advanced maternal age and their most frequent complications in the Maule Region with data obtained between 2017 - 2022 at the Regional Hospital of Talca (RHT).
